[EX Q]: Passage: Colorado River -- Reduction in flow caused by dams, diversions, water for thermoelectric power stations, and evaporation losses from reservoirs -- the latter of which consumes more than 15 percent of the river's natural runoff -- has had severe ecological consequences in the Colorado River Delta and the Gulf of California. Historically, the delta with its large freshwater outflow and extensive salt marshes provided an important breeding ground for aquatic species in the Gulf. Today's desiccated delta, at only a fraction of its former size, no longer provides suitable habitat, and populations of fish, shrimp and sea mammals in the gulf have seen a dramatic decline. Since 1963, the only times when the Colorado River has reached the ocean have been during El Niño events in the 1980s and 1990s.
Question: does the colorado river still reach the ocean

[EX Q]: Passage: The Last House on the Left (1972 film) -- Cunningham served as producer and Craven served as writer and director on the project. Written by Craven in 1971, the original script was intended to be a graphic ``hardcore'' film, with all actors and crew being committed to filming it as such. However, after shooting began, the decision was made to edit the script into a much softer film. This script, written under the title Night of Vengeance, has never been released; only a brief glimpse is visible in the featurette Celluloid Crime of the Century (a 2003 documentary on the making of the film). The crux of the plot is based on the Swedish ballad ``Töres döttrar i Wänge,'' which itself was the basis of Ingmar Bergman's The Virgin Spring (1960), of which Craven was an admirer. Craven envisioned a film in which the violence would be shown in detail onscreen; he felt that many popular films of the era, such as Westerns, glamorized violence and the ``vigilante hero,'' and gave the public a misleading representation of death in the wake of Vietnam War.
